The consequences of climate change are emerging in more visible and more disastrous ways. From climate refugees to diminishing habitats, it seems as though just about every species on planet Earth is ...

New research provides the latest evidence that climate change is having an impact on food webs in high-latitude ecosystems. Biologist Amanda Koltz of The University of Texas at Austin in the Alaskan ...

While kelp forests persist along northern Maine’s rocky coast, kelp abundance has declined by as much as 80% on the southern coast in recent decades. In its stead, carpet-like turf algae have moved in ...

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to ...

This is a preview. Log in through your library . Abstract Stable-isotope ratios of carbon (13C/12C or δ13C) have been widely used to determine the energy base of stream food webs, but such use is ...

My research focuses on understanding the ecological roles of parasites and invasive species in freshwater ecosystems. Current projects are investigating the roles of parasites in food webs, energy ...

Rising temperatures could reduce the efficiency of food chains and threaten the survival of larger animals, new research shows. Rising temperatures could reduce the efficiency of food chains and ...
